Omnidirectional stereovision is beneficial in wide applications due to its large field of view. Traditional implementation of such a system employs two separate cameras looking at separate mirrors to achieve 3D stereo reconstruction. In this paper, a compact omnidirectional multi-stereo system that consists of only one camera and multiple mirrors is proposed. The novelty lies in the designing of a principal mirror above the array of sub-mirrors to achieve multiple omnidirectional stereo pairs that have appropriate baselines and multiple viewpoints in a compact manner. The system's imaging projection and error propagation model are presented. Experiments based on simulation and real data verify the effectiveness of our system.
全向立体视觉因其大视场而在广泛的应用中具有优势。这种系统的传统实现方式采用两个单独的摄像头分别看向不同的镜子以实现三维立体重建。本文提出了一种紧凑的全向多立体视觉系统，该系统仅由一个摄像头和多个镜子组成。其新颖之处在于在子镜阵列上方设计了一个主镜，以紧凑的方式实现多个具有合适基线和多个视点的全向立体视觉对。文中给出了该系统的成像投影和误差传播模型。基于模拟和真实数据的实验验证了我们系统的有效性。
